SPECIFICATION forming part of Letters Patent No. 458,901, dated September 1, 1891.

Application filed February 18, 1890. Serial No. 340.854. (No model.)

.To all whom it may concern:

Be it known that I, ALPHONSE MARIE PIERRE HERVY, of AiXe-sur-Vienne, Department of Haute-Vienne, France, have invented a new and Improved Kerosene-Burner, of which the following is a full, clear, and exact description.

The invention relates to lamps used for kerosene-oil or other liquid fuel.

ro The object of the invention is to provide a new and improved burner which is simple and durable in construction and insures coinplete combustion and permits of easily increasing or diminishing the size of the fiame I5 without producing the obnoxious smell and smoke 'so frequently encountered with the ordinary lamps now in use.

The invention consists in certain parts and details and combinations of the same, as will 2o be described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this speciiication, in which similar letters ot' reference indicate 2 5 corresponding parts in both the figures.

Figure 1 is a sectional side elevation of the improvement, and Fig. 2 is a similar View of the same in a different position and with the wick and other central parts in elevation.

3o The improved burnerA is provided with an inner part B, adapted to be secured to the fonnt of the lamp, and with an outer-'part O, held movably on the inner part B to regulate the iiame of the burner. The inner part B is g 5 provided with a cylinder D, having a central chamber and a closed bottom D and transverse channels E, adapted to be connected with the outside, so as to supply the said central chamber with air for the inside of the 4o flame. The channels E Open at their outer ends onto a ring F, having a horizontally-extending flange secured to the under side of Athe channels E and provided with a threaded .ring F, extending downward from the said flange to screw onto" the fount of the lamp. In the ringF are arranged perforations F2 to permit air from the outside to iiow to the channels E and from the latter to the central chamber formed in the part B by the cylinder 5o D. The outer ends of the channels E are secured in an outer cylinder G7 held at its lower edge to the ring F and provided on its outside at its upper part with a threaded collar G', on which screws a nut H', formed on the curved ring H, extending` downward and fast- 5 5 en ed to the eXteriorringI ot1 the outermovable part C. The ring I is preferably curved outward, as is plainly shown in the drawings, and its lower end rest-s on the outside of the ring F, beingl also provided on its lower part with 6c knobs I for conveniently turning the said ring I and the ring H to screw the nut H up or down on the threaded part of the .stationary cylinder G. The curved ring H is provided with openings H2, and similar openings I2 are formed in the ring I, so that the air from the outside can pass through the said openings I2 and I-I2 and through the openings F2 in the ring F to the interior ot the central chamber. 7o

On the inside of the cylinder G is arranged to slide up and down a cylinder K, connected at its upper end with an outwardly and downwardly curved and perforated flange K', connecting at its outer end with a horizontally- 7 5 extending' flange K2, held on the upper end of the ring I. On this horizontally-extending flange K2 are arranged upwardly-extending projections K3, on which rests the lower end ofthe chimney L, held in place on the said 8o projections by the usual springs N, formed on the upper end of the ring I. The projections Ki", on which the chimney L rests, forms spaces to permit the entrance of air from the outside under the said chimneyand to the interior of the latter over the outside of the perforated and curved iiange K.

From the cylinder K, held to slide in the cylinder G, extends upward the truncated cone O, the upper end of which extends onto 9o the outside of an annular receptacle P, secured to the outside of the cylinder D at the upper end ot the latter. In this receptacle P is placed an indestructible or ineombnstible material Q, connected at its lower edge with the upper end of a wick made in two parts, of which the upper part R is made of a woven fabric, while the lower part R is formed of loose strands passing downward along the sides of the channels E' into the oil or other Ico liquid contained in the fount of the lamp. The part R of thewick is held with its upper of the flame.

edge in contact with the indestructible material Q by means of the hooks S, secured on the outside of the cylinder D, and on which the said woven fabric R is hung, as is plainly shown in the drawings.

The receptacle P is open at its top and is provided on the outside, near the upper end, with openings P. (Plainly shown in Fig. 2.) From this open top and the said openings P issues the flame formed by the burning oil supplied to the incombustible material Q by means of the wick connected by the woven fabric R with the said ineombustible material. When the outer movable part C is in the position shown in Fig. l, the upper part of the conical cylinder O is below the openings P', so that the flame issuing from the said indestructible material Q attains its largest size; but when the part Gis screwed up the size of the flame is diminished by the said cylinder O cutting off the openings P.

In the inside of the cylinder B and near the upper end of the same is supported a smaller cylinder T, provided at its upper end with an outwardly-extending circular flange U, reaching above and over the receptacle P, so that when the movable part C is screwed upward the upper edge of the cylinder is adapted to abut against the under side of the said flange U, as is plainly shown in Fig. 2, to entirely cut off the flame, thereby extinguishing it. From the upper end of the said cylinder T also extends upward and outward a slightly-curved flange V, having perforations and supporting at its upper end an inverted cone V', extending with its apex into the cylinder T, as is plainly shown in Fig. l.

Below the cylinder T is arranged a 'dish WV, having an annular inclined side containing perforations V, through which air from the cylinder D can pass to the space formed between the upper end of the cylinder D and the cylinder T, and from which air can also pass through the cylinder T against the cone V to be deflected through'the perforations in the flange V to the upper part of the inside The air passing to the flame through the space between the cylinders D and T passes to the lower part of the inside of the flame.

The operation is as follows: When the several parts are in the position shown in Fig. 1, the outer part C is in its lowermost position, and when the fuel in the indestructible material is lighted the flame will issue through the side and top openings of the receptacle P and be deflected outward by the flange U of the inner cylinder T. The air necessary for combustion passes through the openings I2 in the ring I and through the openings in the perforated flange K to the outside of the upper end of the receptacle P, while another supply of air passes through the openings in the cylinder F to the channels E, to the interior chamber formed 'by the cylinder D, and through the openings in the perforated side of the dish W to the space between the cylinders D and T, to finally pass to the inside of the flame. Part of this air entering the dish W passes through the cylinder T to be de ilected by the cone V to the upper part of the flame, as previously described. Thus it will be seen that all the air necessary for combustion is furnished both on the inside and the outside of the receptacle P and to the upper end of the flame. that the air passing to the inside ot' the flame is heated before it reaches the same. lVhen the operator desires to lower the flame, he takes hold of the knobs I', so as to turn the movable part C, which then screws upward on the fixed part B, so that the truncated cone O moves over the openings P', whereby this part of the flame is cut off. When the operator still continues this movement, the flame is cut off still more until the flame is finally cut off entirely, and is extinguished when the upper edge of the said cone abuts against the underside of the flange U, so that the air passing up the space between the cylinders T and D has no further outlet.

It will be seen that in this device no wheels, cogwheels,orother si milarmechanism are einployed to raiseI or lower the wick, and at the same time the latter is closed to all exterior openings, so as to avoid leakage of the fuel. The burner can be very easily kept clean, as the several parts can be conveniently removed for the purpose of cleaning, and the fount can be refilled at any time without removing the parts from the fount. It will further be. seen that as the wick is securely held in place by the hooks S it can never fall into the fount, thus avoiding all danger ot explosion by the ignition of the gases by a burning wick droppinginto the fount, as has been frequently the case in the lamps now in use. Itwill further be seen that as the fuel burns through the material in the fixed receptacle P the flame will be constant, requiring no trimming of the wick whatever. As the air passing to the inside of the flame is partly heated before it reaches the same, it furnishes a brightness and a white flame which cannot be well surpassed. As a frequent renewal of the air in the central or inner part of the lamp takes place, a large quantity of the oil can be saved, as the said air assists in complete combustion. The flame can' be increased or diminished without giving the slightest odor of the petroleum. In case it is necessary, the indestructible material held in the receptacle P can at any time be supplied with oil or other suitable fuel.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
